Slow playback in trimmer
Hi,
I bought a new HP Pavilion dm4 Notebook with the following specs:
Intel i5 CPU 2.27GHz
4GB Ram
Win 7 Home Premium (64-bit)
Sony Vegas Pro 9.0e (64-bit)Now, I’m pretty new with Vegas and HD video editing and I thought my notebook would be fast enough. However, when I tried to edit my GoPro h.264 1280×720 60fps clips in the trimmer window, I find that it doesn’t playback well or at all.
In the preview window, there is stil an option to adjust render quality. Is there something like that for the trimmer window? Else, is there any thing I can do to have a smooth playback in the trimmer window, I don’t need it to be sharp since I only need to locate my ins and outs.
An advise would be appreciated!

You can start by NOT shooting at 60fps. You can only deliver 30fps and so you’re asking Vegas to do twice the work for no benefit. I’m guessing that this change alone will smooth out your trimmer preview.
If you need to shoot 60fps because you are doing slow-motion work, then you need to get use to jerky playback because even my 2.66Ghz Quad Core can’t play back 60fps h.264 footage smoothly from my Kodak Zi8.
Also be sure that your project settings match your source footage exactly. Anything else will cause Vegas to conform every frame on-the-fly to match the project which will slow things down.

Chances are the video chip used in the notebook is the problem. Updated drivers may help.

Vegas does not use the GPU at all so it is very unlikely that this is the problem.

Thanks for the advice. It sounds like my notebook just isn’t fast enough. I have to shoot 60fps because of slow-mo work.
Anyway, I think I’ve figured out a way to ‘cheat’ the system. I converted my raw HD files to a frame size that is much smaller (400 x 224)but at the same framerate (60fps). In vegas, I edit using this smaller files to work with, which allows me to edit much quicker, and when I’m ready to render, I close Vegas, replace the small files with the original files (of the same file name) and open Vegas back up again to render.
So far, I’ve done some quick tests and it seems to work quite well… I’ve rendered it in HD and the quality looks about right. But does anyone know if there is something that may go wrong working in this way in the long run?

Actually, there is a product that does this for you. It’s called VASST GearShift and it will swap your files back and forth with just one click. I work at VASST and can help you with any questions.
